对从事放射性操作的人员来说,放射性钴是引起内照射污染的重要来源,尤其是在反应堆设备检修或更换反应堆内壳时,它是引起内照射污染的主要危害。它可以通过呼吸道和胃肠道摄入体内,危害操作人员的健康。由于钴的可溶性化合物经胃肠道的吸收率可高达摄入量的30％左右,所以对已进入接触人员胃肠道部位的放射性钴采取阻吸收措施和促排治疗是很有必要的。 Radioactive cobalt is a significant source of internal exposure pollution to personnel engaged in radioactive operations, and is a major hazard to internal exposure pollution, particularly when servicing or replacing reactor containments. It can be taken into the body through the respiratory and gastrointestinal tract, endangering the health of the operator. Due to the gastrointestinal absorption rate of soluble compounds of cobalt up to about 30% of the intake, it is necessary to take measures to block the absorption of radioactive cobalt into the gastrointestinal tract of contact persons and to promote the treatment of radiotherapy.
